Tony Tony "Cotton Candy Lover" Chopper of One Piece is a doctor and a blue-nosed reindeer who gained human properties by eating the Zoan-type Human-Human Fruit.
Using a self-developed drug he calls Rumble Ball, Chopper can assume more than the three forms provided by his Devil Fruit ability alone. When complimented, Chopper acts really happy while either telling the person who complimented him to stop trying to make him happy, or that Chopper isn't very happy. His voice actress is Ikue Ōtani. In the 4Kids and Funimation English adaptations, his voice is supplied by Lisa Ortiz and Brina Palencia, respectively.
